PURPOSE:To effectively impart an impact force to a piezo-electric element by containing the element in an actuator slidably urged and containing a driving spring and a hammer in a secured container. CONSTITUTION:A pressing force is externally applied to an actuator 11, and the actuator 11 is slidably engaged within a container 17 fixedly installed. An impact force is imparted to a piezo-electric element 12 by a hammer 19 to generate high voltage at the element 12. The element 12 is contained in the actuator 11, and the hammer 19 is contained together with driving spring 18 in the container 17. The high voltage generated at the element 12 is picked up through intermediate electrodes 15. |
